squid lento, antes funcionava agora tá com erro. Todos os dados no tópico
Salve geral!
tenho um cache em freebsd rodando squid.
Funcionava as mil maravilhas mas no ultimo mês começou a apresentar problemas e lentidão sem explicação.
A máquina que rodo o sistema é um xeon 2.8, 2gb ram, hd 73gb sas. (servidor HP prolion ml110 g5).
ao todo tenho 550 clientes jogando requisições nele (apenas porta 80, pois o redirecionamento está sendo feito pelo mikrotik).
Segue configuração atual:

Os clientes alegam que ao abrir uma página algumas vezes 40 a 50% ela fica carregando por um bom tempo mas ao dar f5 abre de vez.
meu link é de 14mb mas nao uso 10mb. Ou seja atualmente está melhor desativar o cache enquanto resolvo esses problemas.
alguem tem uma luz??
